ABSTRACT:
A mud dehydrating system is provided. The system includes a table, a centrifugal dehydrating cylinder, endless upper and lower filter cloths, compressing rollers, and a cleaning and washing unit in combination. The cleaning and washing unit has swingable nozzles to spray a strong stream of water on the filter cloths. The cloths are pulled tight by tensioning rollers. Two front compressing rollers have long annular recesses formed therein, into which the filter cloths fit for increasing the mud mass to be compressed for dehydrating and preventing the mud mass from leaking out from the sides of the cloths. The tensioning rollers are moved by a pressure augmenting unit for maintaining a stable pulling force on the tensioning rollers to pull the filter cloths stably for a long period of time.
